I am just now using a philips filament bulb. My eyes arent twitching, i cant see a flicker, no nausea. I just tested it a few hours, but my eyes are totally sore from work and still not acting up. It means no flicker or acceptable flicker. It is not dimmable, but not super bright when postioned behind you, so it is usable as ambient light for my PC, perhaps in the living room. It is still not the same color temperature as a normal light bulb, but acceptable.

I will test it another few days and as soon as i get the other 3 light bulbs i will share again.
